<span>Early civilizations lacked the
expertise needed to construct the elaborate works necessary to modify
the land for their own use, such as massive irrigation systems or graded
tunnels and roads to pass through natural barriers. The earliest cities
were established in geographically beneficial areas, providing their
citizens with ready access to the natural resources they needed. Egypt,
for instance, enjoyed a massive agricultural benefit from the regular
flooding of the Nile River, as well as protection from other
civilizations created by the deserts and harsh terrain that surrounded
the kingdom. Rivers and sea currents provided established trade routes
between these civilizations and encouraged trade, while mountains acted
as cultural barriers and allowed the people on either side autonomy from
one another. Later civilizations learned to take advantage of geography
to suit their needs, allowing for colonization of areas previously
unsuitable for human habitation.</span>
The megaliths can simply be defined as large stones that are forming a monument from the prehistory, or are part of a monument of the prehistory. There are numerous megaliths found around the globe, with some being more famous than others, such as Gobekle Tepe and Stonehenge. All of the megaliths are surrounded in mystery, as the historians still can not provide proper answers about their building, or the transportation of these stones, as they have been brought from areas far away from where they have been built. The main theories are that they have been built fro either astronomical purposes, or for religious purposes. The transportation of these stones is still subject of hot debate, with theories that wood has been used for their transportation, the rivers have been used (where there are rivers), some technology that still has not be defined about this period of time.
